Futuristic Starship Designed for 250-Year Journey to Alpha Centauri
6 Aug
Summary
- 36-mile long cylinder with biomes, food, libraries, parks, and more
- Powered by nuclear fusion, with artificial gravity from rotating cylinders
- Aims to safely deliver passengers to Proxima Centauri b, 4 light-years away

On August 6th, 2025, a groundbreaking design for a futuristic spacecraft capable of transporting around 1,000 humans on a 250-year journey to the Alpha Centauri star system has emerged as the winner of the global Project Hyperion design competition. The 36-mile long cylindrical vessel, named 'Chrysalis', features a range of biome ecosystems, food production facilities, libraries, parks, multi-story living areas, schools, hospitals, and sports complexes to sustain its passengers over the centuries-long voyage.
Powered by nuclear fusion reactors and utilizing a series of rotating concentric cylinders to generate artificial gravity, the Chrysalis is designed to safely deliver its inhabitants to the surface of the exoplanet Proxima Centauri b, located 4 light-years from Earth. The ship's mission objectives include preserving the cultural, biological, and technological heritage from Earth while establishing a new human settlement on the distant world.
One of the most impressive features of the Chrysalis is its 130-meter-high 'cosmos dome', which allows the inhabitants to observe the external environment of deep space through its glass panels as they float freely around. This dome will also serve as the venue for the annual Chrysalis Plenary Council, where all the passengers gather to discuss the ship's progress and future plans.
